The high-end economy lines GSN & GFE combine powerful with economic efficiency: both lines are also equipped with helical ground gears, ensuring a minimum noise level and smooth running. The entire needle bearing has been especially designed to reach high torques that beat the competition for devices of the same size. All planetary carriers are produced as a cage made from solid materials. This increases silent operating characteristics while at exactly the same time improving positioning precision and reducing backlash. An additional shaft sealing ring ensures maximum dirt and splash water safety relative to protection course IP65 in every lines.
One way to reduce backlash is by using precision gears. The focus on manufacturing in precision gears can be tighter tolerances, so all over the gear will be a tighter, more exact suit. And the tighter match means less play in the gear teeth, which may be the cause of backlash to begin with. Of program, precision gears are more costly, if the application demands high accuracy, after that precision gearing could be the way to go.
From a equipment design perspective, a simple way to reduce backlash is to make sure one’s teeth mesh tightly together. That is typically performed by shortening the center distance between gears. For pre-loading, this is often done using a spring mechanism to hold the gears firmly set up. This also eliminates the enjoy between the gear teeth and thus eliminates backlash.
Of course, the type of gears used may also have a huge impact on the quantity of backlash. So for example, some equipment types such as strain wave gears, or harmonic equipment drives, possess zero backlash.

The GSD, GSB & GSBL high-end gearbox lines are constructed in a space-optimized, two-stage design. Due to the lower torque ideals, the input stage is definitely dimensionally smaller compared to the result stage. Its short style makes the GSD series the ideal high-end gearbox for space limited applications. The low regular backlash of the GSD collection makes it the perfect fit for highly powerful applications where highest positioning and speed accuracy is required. The flange result produces highest torsional rigidity. For the lodging of particularly high axial loads, taper roller bearings are elective in sizes with 90 mm diameter or more. The GSB line means high performance in mixture with low backlash and high precision. Its robust, one-piece housing permits a higher gearbox rigidity and the absorption of high radial and axial loads. The angular gearboxes of the GSBL series offer the same advantages as the GSB series; the right angle shape makes the GSBL collection the perfect match for all dynamic applications where space is bound.
